Even if it is as vague as you suggest, though, how is this categorically different from es-419? That is at least as vague if not more so, yet nobody (now) debates the utility of that tag. 

As far as I understand, the difference between varieties of es-419 is lexical (using “tu” or “usted” or “vos”) and not in any way orthographic — unless Central American imperative forms like “hablá” are normative.
